It seems to me libtool does not override path. It should prepend 
projects specific paths to environment variable.
Existing code:
...
     # Add our own library path to $shlibpath_var
     $shlibpath_var=\"$temp_rpath\$$shlibpath_var\"
...

I'm not convinced that patch is correct.
Let project build new version of a system library and try to perform 
some tests. Executable from regression tests should use library from 
"build tree" not system one.
